As this form isn't a multipart one, maybe you can simply use : http://curl.haxx.se/libcurl/c/http-post.html

CURL *curl;
CURLcode res;

/* In windows, this will init the winsock stuff */ 
curl_global_init(CURL_GLOBAL_ALL);

/* get a curl handle */ 
curl = curl_easy_init();
if(curl) {
  /* First set the URL that is about to receive our POST. This URL can
   just as well be a https:// URL if that is what should receive the
   data. */ 
  curl_easy_setopt(curl, CURLOPT_URL, "http://postit.example.com/moo.cgi");
  /* Now specify the POST data */ 
  curl_easy_setopt(curl, CURLOPT_POSTFIELDS, "m-address=your@mail.com");

  /* Perform the request, res will get the return code */ 
  res = curl_easy_perform(curl);
  /* Check for errors */ 
  if(res != CURLE_OK)
    fprintf(stderr, "curl_easy_perform() failed: %s\n",
          curl_easy_strerror(res));

  /* always cleanup */ 
  curl_easy_cleanup(curl);
}
curl_global_cleanup();
